When all of them had their fill of moonbeams and grasses, of running and playing games, the Doctor contacted the attendant for accommodations for the evening, everyone relaxed and at peace. Jack was holding a sleeping Bella in his arms, smiling down at her as he pressed a light kiss to her eyelids.

"Sometimes I forget she was ever this young," he whispered quietly, carefully handing her off to her father, "Oh, the trouble you have to look forward to, River," he teased with a wide grin on his face.

"Hmm. I can imagine," she replied with an equally fond expression.

Suddenly, just as the attendant was approaching them with their keys, Jack yelped before pulling a communication device from his long coat. After reading whatever message was on it, he began typing in coordinates into his, repaired, the Doctor noted, vortex manipulator.

"Ah- gotta go. That'll be the ol' ball and chain's calling," then he caught sight of the Doctor and Rex's glares and everyone else's looks of surprise, "I meant better half," he laughed out in amusement, still chuckling as he began hugging everyone (too enthusiastically in the opinion of some) goodbye.

"Mmm, where'd you meet this one, Jack? On a meteor, in a bar, during a fight? Love at first punch? Sneaking off to a different century during the stag party?" River rolled her eyes, well familiar with the Captain's history, as she shook her head with a soft, knowing smile at his newest love interest.

"Worse than that, River. I actually made it to this wedding," he said, dramatic and obviously false grimace marring his face before it was replaced with a smile that seemed to emanate from deeper within him than she'd seen in ages. He winked as he shot down her teasing comments, surprising her more than a little.

"Wait- did I just hear correctly?! Jack Harkness actually, legally married?" River's voice rose incredulously as she gaped at him.

"Very much so. In fact- wait, no of course you wouldn't know-" he looked up to see the Doctor give the slightest shake of his head as he turned to put his daughter to bed with Amy and Rory for the night, shaking Canton awake as they went. Then Jack turned back to grin at her. "Wow, so young River! Can't even believe I've been made an honest man!"

"Honest? Never. Now man has never been in question," she said in a flirtatious tone.

He winked again at her before they both broke out in laughter as Jack bent and kissed her temple, hugging her tightly.

"No, I really mean it. This one's... very different to any of the others. It's more... lasting. The two of us- we're fixed," he finally decided with a dreamy smile and a nod to himself, while Rex simply rolled his eyes behind him, this time with the slight smirk of an old friend who's heard all this before- repeatedly.

"Indeed?" River raised a questioning eyebrow at Jack.

"Yes," he assured her, meeting her gaze and for the first time that night completely and utterly sincere.

She stared into his eyes and saw a love she was excruciatingly familiar with in them, and it caught her completely off guard. Then the moment broke and they both chuckled before their light banter was back.

"So, do I know this mysterious person who managed to actually pin down the Captain Jack Harkness?"

His smile widened, relishing the rare moment when he knew more than her.

"Ooh- I really couldn't say. Well, I suppose- say, when's the last time you saw me, anyway?" he changed the subject abruptly.

"Met your brother a while back. Interesting fellow." They both grimaced at this, unpleasant memories coming to the surface.

"Yeah, suffice it to say, he wasn't invited to the wedding."

"Really? I would have thought he'd be best man," she threw out in a far lighter tone than the experience warranted.

"He didn't have a proper suit," he joked back. "No, the best man was... wow, these spoilers are harder than they seem, aren't they Song?" Then he looked at her apologetically, shaking his head before asking if they wouldn't mind taking Rex home, or wherever he felt like going next.

"Anything for you, Jack, you know all you have to do is ask." Then she looked up at him with a soft smile, confusing him as he looked at her enquiringly, "It's just... I can't really picture it. Jack Harkness- husband extraordinaire."

He threw his head back and laughed at the description, nodding enthusiastically in agreement.

"I hope so, River. I really do hope so. And, you most definitely will someday- picture it..." Then they hugged tightly as he suddenly ran off, his coat billowing behind him. "Got to go, don't like to keep her waiting!"

"Her?" she nudged, hoping to squeeze more information from him.

He just winked at her and ran off.

"Tell the Doctor- I'm not apologizing- not for this one!" he shouted as he disappeared, leaving an incredulous River with a soft smile on her face, happy for her friend's future joy.

A/N- Just another short chapter where I get to leave you all speculating. It must really be frustrating to River and the Doctor actually have to live their lives so vaguely... Anyway- next comes more fluff! Oh, and let me know what you think about Jack, so I can get him right for future (or past) meetings.
